A spreadsheet, also known as a worksheet, is a document with rows and columns that is used to easily sort, organise, and arrange data as well as calculate numerical values.

The ability of a spreadsheet software program to compute numbers using mathematical formulae and the information in cells is what distinguishes it from other programs. Making a summary of your bank's balance using a spreadsheet is one example of how it might be put to use.

Because spreadsheet, workbook, and worksheet functions are so similar, it might be challenging to distinguish between them. You open a workbook when you launch Microsoft Excel, a spreadsheet application.

The most perplexing thing is that a worksheet and a spreadsheet are often used interchangeably. In other words, the terms "spreadsheet" and "worksheet" are interchangeable. However, the majority of users just refer to the application as a spreadsheet tool and the files it generates as worksheets.

Answer:

function is a self-contained program segment that carries out some specific, well-defined task. Every C program consists of one or more functions. One of these functions must be called main. Execution of the program always begins by carrying out the instructions contained in main. Note that if a program contains multiple functions then their definitions may appear in any order. The same function can be accessed from several different places within a program. Once the function has carried out its intended action, control is returned to the point from which the function was accessed. Generally speaking, a function processes information passed to it from the calling portion of the program, and returns a single value. Some functions, however, accept information but do not return anything.

A function definition has two principal components: the first line (including the argument declarations), and the so-called body of the function.

The first line of a function takes the general form data-type  name(type 1  arg 1,  type 2  arg 2,  ...,  type n  arg n)

where data-type represents the data type of the item that is returned by the function, name represents the name of the function, and type 1, type 2, ..., type n represent the data types of the arguments arg 1, arg 2, ..., arg n. The allowable data types for a function are:

int       for a function which returns an integer value

double    for a function which returns an floating-point value

void      for a function which does not return any value

The allowable data types for a function's arguments are int and double. Note that the identifiers used to reference the arguments of a function are local, in the sense that they are not recognized outside of the function. Thus, the argument names in a function definition need not be the same as those used in the segments of the program from which the function was called. However, the corresponding data types of the arguments must always match.

The body of a function is a compound statement that defines the action to be taken by the function. Like a regular compound statement, the body can contain expression statements, control statements, other compound statements, etc. The body can even access other functions. In fact, it can even access itself--this process is known as recursion. In addition, however, the body must include one or more return statements in order to return a value to the calling portion of the program.

A return statement causes the program logic to return to the point in the program from which the function was accessed. The general form of a return statement is:

return  expression;

This statement causes the value of expression to be returned to the calling part of the program. Of course, the data type of expression should match the declared data type of the function. For a void function, which does not return any value, the appropriate return statement is simply:

return;

A maximum of one expression can be included in a return statement. Thus, a function can return a maximum of one value to the calling part of the program. However, a function definition can include multiple return statements, each containing a different expression, which are conditionally executed, depending on the program logic.

Note that, by convention, the main function is of type int and returns the integer value 0 to the operating system, indicating the error-free termination of the program. In its simplest form, the main function possesses no arguments. The library function call exit(1), employed in previous example programs, causes the execution of a program to abort, returning the integer value 1 to the operating system, which (by convention) indicates that the program terminated with an error status.

The program segment listed below shows how the previous program factorial.c can be converted into a function factorial(n) which returns the factorial (in the form of a floating-point number) of the non-negative integer n:

double factorial(int n)

{

 /*

    Function to evaluate factorial (in floating-point form)

    of non-negative integer n.

 */

 int count;

 double fact = 1.;

 /* Abort if n is negative integer */

 if (n < 0)

  {

   printf("\nError: factorial of negative integer not defined\n");

   exit(1);

  }

 /* Calculate factorial */

 for (count = n; count > 0; --count) fact *= (double) count;

 /* Return value of factorial */

 return fact;      

}

The primary difference between WPA2-Personal and WPA2-Enterprise is in how the authentication process is handled.

WPA2-Personal uses a pre-shared key (PSK) method for authentication, where all users share the same password. This method is suitable for small home networks where there are a limited number of users.

On the other hand, WPA2-Enterprise uses a more complex method of authentication, such as the Extensible Authentication Protocol (EAP), to authenticate each individual user on the network. This method is more suitable for larger organizations with many users, as it provides greater security and control over network access. Additionally, WPA2-Enterprise requires the use of an authentication server, such as a RADIUS server, to manage user authentication.

Answer:

A. Encode the (negative) decimal fraction -9/2 to binary using the 8-bit floating-point notation.

First, let's convert -9/2 to a decimal number: -9/2 = -4.5

Now, let's encode -4.5 using the 8-bit floating-point notation. We'll use the following format for 8-bit floating-point representation:

1 bit for the sign (S), 3 bits for the exponent (E), and 4 bits for the mantissa (M): SEEE MMMM

Sign bit: Since the number is negative, the sign bit is 1: 1

Mantissa and exponent: Convert -4.5 into binary and normalize it:

-4.5 in binary is -100.1. Normalize it to get the mantissa and exponent: -1.001 * 2^2

Mantissa (M): 001 (ignoring the leading 1 and taking the next 4 bits)

Exponent (E): To store the exponent (2) in 3 bits with a bias of 3, add the bias to the exponent: 2 + 3 = 5. Now, convert 5 to binary: 101

Now, put the sign, exponent, and mantissa together: 1101 0010

So, the 8-bit floating-point representation of -9/2 (-4.5) is 1101 0010.

B. Determine the smallest (lowest) negative value which can be incorporated/represented using the 8-bit floating-point notation.

To get the smallest negative value, we'll set the sign bit to 1 (negative), use the smallest possible exponent (excluding subnormal numbers), and the smallest mantissa:

Sign bit: 1

Exponent: Smallest exponent is 001 (biased by 3, so the actual exponent is -2)

Mantissa: Smallest mantissa is 0000

The 8-bit representation is 1001 0000. Converting this to decimal:

-1 * 2^{-2} * 1.0000 which is -0.25.

The smallest (lowest) negative value that can be represented using the 8-bit floating-point notation is -0.25.

C. Determine the largest (highest) positive value which can be incorporated/represented using the 8-bit floating-point notation.

To get the largest positive value, we'll set the sign bit to 0 (positive), use the largest possible exponent (excluding infinity), and the largest mantissa:

Sign bit: 0

Exponent: Largest exponent is 110 (biased by 3, so the actual exponent is 3)

Mantissa: Largest mantissa is 1111

The 8-bit representation is 0110 1111. Converting this to decimal:

1 * 2^3 * 1.1111 which is approximately 1 * 8 * 1.9375 = 15.5.

The largest (highest) positive value that can be represented using the 8-bit floating-point notation is 15.5.

Answer: 2: Use the subject line wisely to let your reader know the main purpose of the e-mail.

============================================================

Explanation:

The subject line is like the title of a book. You want to give a quick sense of what the email is about, but you also don't want to put the entire contents of the book in the title. The subject line only has so much room. Even less room is available if the reader is checking their email on their mobile device.

Choice 1 is false because subject lines are important. I can't think of a case where you can omit the subject line entirely (ie leave it blank), unless it's a situation where the recipient knows in advance what the topic is about. Though that may be rare.

Choice 3 is false. Yes you want to keep the subject line short, but you also don't want to be cryptic or confusing. If you can get away with using 1 or 2 words, then go ahead and do so. However, you may need more words to convey the topic of the email. Go with what feels right and try to put yourself in the shoes of the person reading your email. Ask yourself "Does this convey the message I want to send?"

Choice 4 is false. As mentioned, you do not want to put the entire email in the subject line. The exception of this rule is that if the email is really really short. For every other case, you should have a fairly short title and then go over the details in the email main body itself.

Use the subject line wisely to let your reader know the main purpose of the e-mail.
